Abstract
The routine metabolic rate of Pseudocrenilabrus multicolor victoriae, laboratory-reared, F1 offspring of parents collected from a hypoxic swamp, did not differ between sibs raised under normoxia and hypoxia. In the offspring of parents originating from a river where the oxygen levels were generally high but fluctuating, the metabolic rate of fish raised under normoxia was higher than for sibs raised under extreme hypoxia. Although further experiments with a larger random sample of the parental stock will be necessary to validate the patterns, the difference between the experiments may indicate the selective environment of the parents. © 2002 The Fisheries Society of the British Isles.
